The "Excel Series Angular Ball Bearing with Seal" is a product that utilizes the Excel seal, which has a proven track record in deep groove ball bearings. It enhances sealing performance and securely retains the enclosed grease, preventing the intrusion of foreign substances from the outside. This allows for maintenance-free operation, providing peace of mind during use. Pre-load adjustment (GM) has been performed in advance, so there is no need for troublesome adjustment work when assembling it into machinery, enabling a reduction in labor costs. 【Features】 ■ Sealed with a seal ■ Pre-greased ■ Energy-efficient ■ Easy assembly ■ Low noise *For more details, please download the PDF or feel free to contact us.

The "EXS1" is a thrust self-aligning roller bearing that achieves a long lifespan through the use of high-purity steel. It realizes one of the world's highest permissible rotational speeds due to low temperature rise. Additionally, it is compatible for use not only in vertical axes but also in horizontal axes. By optimizing the holder's posture during operation, it minimizes temperature rise. In particular, the temperature rise during grease lubrication in horizontal axes is significantly reduced compared to conventional products. 【Features】 ■ Adoption of large diameter rollers achieves one of the world's largest high load capacities. ■ Long lifespan achieved through the use of high-purity steel. ■ One of the world's highest permissible rotational speeds achieved through low temperature rise. ■ Uniform stress distribution through optimized raceway curvature. ■ Compatible with operating temperatures up to 200°C. ■ Compatible for use in both vertical and horizontal axes. *For more details, please download the PDF or feel free to contact us.

The "TAB" is a high-durability ball screw support bearing with long life and high reliability. It adopts a triple lip structure, improving dust resistance and grease retention. It achieves energy savings through light contact. Additionally, it is strong against surface damage caused by impact loads and fretting, demonstrating excellent durability even in environments where foreign substances may enter. 【Features】 ■ Long life and high reliability (Multi-Tough specification) ■ Significant improvement in rolling life due to the adoption of special heat treatment ■ Improved dust resistance and grease retention with a triple lip structure ■ Achieves energy savings through light contact ■ Uses grease that is resistant to coolant intrusion and fretting ■ High rigidity is achieved by a contact angle of 60 degrees and an increased number of balls *For more details, please download the PDF or feel free to contact us.

The "TAF-X" is a high-load capacity ball screw support bearing that uses the largest possible steel balls within limited main dimensions. The contact angle has been changed to between 50 and 55 degrees, achieving a high axial dynamic load rating. The raceway shoulder diameter and raceway radius have been optimally designed to significantly increase the axial limit load. Additionally, by optimally designing the preload amount, the torque has reached a level comparable to conventional products. 【Features】 ■ Increased thrust load capacity ■ Increased axial limit load ■ High rigidity ■ Low torque ■ Sealed *For more details, please download the PDF or feel free to contact us.

The "EXQ" is a self-aligning roller bearing with high axial load resistance performance. By stabilizing the roller posture during rotation, it reduces the heat generation of the bearing and achieves one of the highest permissible rotational speeds in the world. Additionally, by optimizing internal specifications and using high-purity steel, it realizes a long service life. It comes standard with thermal stabilization treatment and can be used up to 200°C. We also offer the EXQ-V specification, which has high impact resistance performance. 【Features】 ■ Significantly improved axial load resistance performance ■ Achieves one of the highest permissible rotational speeds in the world ■ Realizes a long service life ■ Standard thermal stabilization treatment, usable up to 200°C ■ EXQ-V specification with significantly improved impact resistance of the retainer ■ Adopts a free guide ring that controls roller posture *For more details, please download the PDF or feel free to contact us.

"Quest" is a deep groove ball bearing that explores high functionality and reliability. In recent years, there has been a trend towards higher speeds and temperatures in the industrial machinery sector as application performance improves. This bearing exhibits high robustness, allowing it to flexibly adapt to such environmental changes. The newly adopted heat-resistant nitrile rubber ensures sealing performance in higher temperature ranges. Improvements in base oil have enhanced its robustness for high-temperature applications. 【Features】 ■ High robustness that flexibly adapts to environmental changes ■ Standard adoption of heat-resistant seals ■ NACHI's unique high-performance grease ■ Enhanced high-temperature robustness through improvements in base oil ■ Approximately double grease lifespan confirmed under semi-high temperature conditions of 120°C ■ Compliant with European ELV and RoHS directives *For more details, please download the PDF or feel free to contact us.
